Yuav Ua Li Cas Ntsuas Frictional Heat yuam kev hauv cov neeg ua haujlwm kub

Qhov sib txawv ntawm qhov kub thiab txias tau sau tseg rau ntawm qhov kub khiav thiab qhov kub ntawm qhov kub yuav tsum tau muab piv nrog rau cov txheej txheem kev tsom xam, txhawm rau txiav txim siab qhov kev sib txhuam ntawm cov cua sov hauv cov kub khiav. Txhawm rau ntsuas qhov ntsuas qhov system, cov tub ntxhais yuav tsum txiav txim siab qhov tseeb ntawm qhov ntsuas kub.

 

1. Direct Measurement Method: Sib piv ntawm Melt Temperature (Muaj tseeb tshaj)

Siv lub ntsuas kub kub: txhawm rau txhawm rau ntsuas qhov ntsuas kub ntawm cov yas yaj, nruab ib qho kev ntxig rau - hom melt kub sensor (xws li K-hom thermocouple) ntawm lub qhov hluav taws xob pwm lossis lub qhov hluav taws xob khiav;

Sau qhov kub khiav qhov ntsuas kub ib txhij los ntawm kev nyeem cov channel uas cuam tshuam cov zaub tus nqi ntawm tus kub khiav kub tswj;

Txiav txim siab qhov ua yuam kev los ntawm kev rho tawm qhov tseeb yaj qhov kub ntawm qhov kub khiav qhov ntsuas kub (kev sib txhuam kub yuam kev).

Cov ntaub ntawv siv tau: Hauv kev tsim khoom siv kho mob catheter, qhov kev sib txhuam ntawm qhov hluav taws xob yog +22 degree, qhov tseeb ntawm qhov kub yog 278 degree, thiab qhov kub khiav qhov ntsuas kub yog 300 degree.

 

2. Infrared Thermal Imager Scanning raws li ib qho kev txheeb xyuas ncaj qha

Kev Tshawb Fawb nrawm tom qab kaw: Tom qab siab -kev txhaj tshuaj molding ceev, qhib pwm thiab sai sai scan tus kub khiav qhov kub ntawm qhov chaw faib khoom siv ib qho infrared thermal imager.

Kev sib piv ntawm Steady-Lub Xeev Kub: Cov qib ntawm kev sib txhuam ntawm cov cua sov yog qhia los ntawm qhov sib txawv ntawm qhov kub thiab txias nyob rau hauv dynamic tej yam kev mob thiab qhov kub thiab txias thaum lub sij hawm static heat preservation.

Nrhiav Cov Chaw Kub Kub: Nrhiav qhov kub tsis txawv txav hauv qhov siab -shear thaj chaw, xws li lub taub hau ntawm lub taub hau thiab ntws faib lub khob hliav qab.

Lus Cim: Kev ntsuas kub tsis tuaj yeem hloov tau los ntawm txoj kev no, txawm hais tias nws tsim nyog rau kev ntsuam xyuas thawj zaug.

 

3. Tsawg-Speed ​​vs. High-Speed ​​Conditions Process Comparison Method

Ob Qhov Kev Txhaj Tshuaj Ceev:

Tsawg-Speed ​​Filling (<50mm/s): The measured temperature is near to the actual heating temperature, and frictional heat is minimal.

Filling at a high speed (>200 mm / s) ua kom muaj kev sib txhuam ntau heev.

Temperature Difference Recording: Kev koom tes ntawm kev sib txhuam ntawm cov cua sov yog sawv cev los ntawm qhov sib txawv ntawm qhov kub thiab txias ntawm tib qhov chaw ntawm qhov siab thiab qis qis.

Cov txiaj ntsig: Tsim nyog rau kev ceev ntawm - qhov kev ntsuam xyuas qhov chaw; tsis xav tau cov cuab yeej ntxiv.

 

4. Kev ntsuas kev nyab xeeb thiab kev tswj xyuas yuam kev

Cov tshuaj tiv thaiv lub sij hawm: Txhawm rau tiv thaiv lag, xaiv cov thermocouples ceev nrog lub sijhawm tshuaj tiv thaiv tsawg dua 0.5 vib nas this;

Qhov chaw ntsuas kub qhov sib xws: txhawm rau txo qhov sib txawv, xyuas kom qhov chaw ntsuas qhov sib npaug txhua zaus;

Kev Kho Cov Khoom Siv Hluav Taws Xob: Siab- cov ntaub ntawv viscosity, xws li PC thiab ABS, muaj qhov tsis raug ntau dua thiab yuav tsum tau ntsuas nyias;

Kev Tshawb Fawb Ntau zaus: Txhawm rau tsim cov ntaub ntawv tsis raug them nyiaj, rov ntsuas txhua lub hlis twg lossis ua raws cov txheej txheem hloov kho.

Txoj Cai Kev Nyab Xeeb: Kom nkag siab tag nrho cov kev sib txhuam ntawm cov cua sov yuam kev, "kev ntsuas melting + txheej txheem sib piv + calibration tsis tu ncua" yuav tsum tau ua ke.
